The 3rd day of Lollapalooza started off strong. Sunday began with London's Bombay Bicycle Club performing songs off A Different Kind of Fix and Flaws. The large crowd in attendance baking in the hot sun on The RedBull Soundstage. (Although some concert goers discovered areas of shade a ways from the stage, but enough to hear their favorite bands play.

That same sage would be host later in the after noon the Icelandic band Sigur Ros. With a string section and use of a bowed guitar, their sound was unique and calm. Although there was no pronounced moshing for this band (though, some concert goers always seem to find a way) their performance received rave reviews and cheers when all was said and done.

Doctor P proved to be another Dub-Step favorite in the largest Perry's stage of all time, with crowd favorites "Big Boss", and "Watch Out" meeting with bouncing, fist pumping and hands waving. However when the all familiar Nintendo "Tetris" theme played, everyone rejoiced as one of his most popular songs captured everyone’s attention in the hour long set.

The Gaslight Anthem Rocked the Google Play stage, litterly as the hard rock quartet played a great set including their latest song "45". The area around the stage absolutely jampacked. Meanwhile for the Hip-Hop afficinado J. Cole was about to "Blow Up" on the Bud Light stage to a huge crowd, performing to over 10,000 fans.

At The Drive In, appeared on the Redbull Sound Stage at 6pm, with a huge crowd, and big mosh pit. Everyone seemed to enjoy the hour long set, although it seemed obvious that they were all waiting for their most popular song "One Armed Scissor" which was delivered as expected last. It didn't disappoint. Their position in rock history will go down as a band that was the influence, but not the projection of the success. Meanwhile Florence Welch brought out her machine for a spin on the Bud Light Stage for over an hour. Some of the songs adjusted after reports of Florence's issues performing the songs live, but an amazing set live.

It was the worst feeling to leave Lolla without playing yesterday and the BEST feeling to announce we WILL PLAY LOLLA tonight at 7:30!

The Band Chairlift , initially bumped due to Saturday's Evacuation got a chance to reschedule and play Sunday, on the Google Play Stage. The Brooklyn New York band is most known for their iPod commercial song "Bruises" Mike Snow delighted many as the last act to play the Sony stage for the 2012 Effort of Lollapaloza, playing their song "Animal", many in the outskirts of the stage knew the song, but wasn't sure where from.

On the North side of the festival Actor/Comedian Donald Glover from 30 Rock performed his serious and legimiate Rap Act, offering a sharp contract to other acts, wtih the entire crowd engaged and singing along

The night ended with most of the festival witnessing Jack White, do his thing. Jack delivered a solid two hours on the Redbull Soundstage, however the crowd between 50,000-70,000 wanted the songs that made him famous. So everyone waited through a complete switch out of band members (35 minutes into the set Jack Traded his all-Male band to an all-female band) Finally with a half hour to go, we heard "Seven Nation Army" "Fell In Love With A Girl" "The hardest button to button" and more of the songs that allowed Jack to be Jack on the biggest stage and the last night of a great brand that is Lollapalooza Chicago.

For the first time in Lollapalooza history, rain forced the evacuation of over 70,000 people from Grand Park as howling winds up to 70 MPH, whipping rain and dangerous lighting rolled through Downtown Chicago Saturday afternoon for day two. The challenge of evacuating the masses was no small task, announcements were made from all stages. Three evacuation locations were set up to receive the incoming traffic, as were, albeit unwillingly, the hotels across the street from Grant Park.

The festivals remarkable social media integration proved to be a key factor in keeping concert goers informed with the event status. Utilizing Facebook, Twitter and their own custom Lollapalooza Android and IPhone App, they were able to push updates to their over 100k followers.

ATTENTION: Serious weather is about to hit Grant Park. ALL festival goers must evacuate IMMEDIATELY. Head to our 3 evacuation locations NOW.

The festival organizers Fresh And Clean Media and C3 Presents handled the evacuation quite professionally, there were no reported cases of an unruly crowd. Everyone retreated during the storm, waiting to get the "All Clear" from Lolla.

The all clear came at 6pm when the gates reopened in Downtown Chicago to the Star Wars Theme (The same theme they used the first day the gates open). It was as if someone had pushed the "Reset Button" and we were all coming into a fresh day of music, food, and fun. Since at least 70% of the festival was outside waiting to get in all at once, the normal wristband scrutiny was thrown out the window. The loose gates allowed many a non ticket holders the chance to experience #Lolla, perhaps they bought a t-shirt or Lobster Corn Dog, we can only pray

Sorry Chicago, we were really pumped to play for you all but the storm had other plans. We will be back to make it up for you!

Some not so lucky artists were bumped off the bill due to the weather delay. Alabama Shakes who's popularity has been growing since the April release of Boys & Girls, along with notable TV appearances were among the list of of mother nature’s fury. The Temper Trap another crowd favorite was also bumped from the 3 day extravaganza. They performed later that night at Park West in Lincoln Park.

Unfortunately @thetempertrap's performance at @lollapalooza was rained out today. The official after show at Park West is still going ahead

Earlier in the day the sun was shining and the early attending crowds were treated to San Diego's Delta Spirit Performing songs from History From Below, Waits Room and their self-titled effort that was released this past March. Showing an amazing effort on the Bud Light Stage, the festivals 2nd largest, was Franz Ferdinand with a great set list and melodic rhythm they look and felt like a headliner. Since the evacuation ate up prime time hours on the schedule, the City of Chicago granted a curfew extension to 10:45pm (An extra 45 minutes) at 9:03pm at long last the performance from Day 2's headliners The Red Hot Chilli Peppers proved to be just what the doctor ordered. With chart toping radio hits you heard first on 103.1 The Buzz. such as newer favorites "Look Around", " Monarchy of Roses", and classics such as "Can't Stop,", "Otherside,", "Suck My Kiss", "Around the World", "Snow (Hey Oh)," and of course "Under The Bridge"
